How it works:
The lamp is controlled by infra-red (IR) radiation.
Infra-red radiation is emitted by the sun, remote controls and artificial light sources
such as incandescent and halogen lamps. By contrast, fluorescent lamps emit very
little IR radiation once they have reached their normal operation state. The light from
such lamps does not interfere the IR sensor which could make the lamps flicker or go
off.
In the case of sunlight, it can be assumed that the brightness of the visible light is
proportional to the intensity of the infra-red radiation. The two sensors on the lamp
(behind the red covers) detect the IR radiation in the vicinity of the lamp. A measure-
ment signal is derived from this, and this signal is then evaluated by the electronic
circuitry in the lamp:
Self-test each time power is applied.
A complete lamp test is performed. All the components of the lamp are checked for
correct operation. The lamp will light after about two seconds to indicate that the test
has been successfully completed.
